Get to Know Louis

Louis Foster is coming off a 2025 NTT INDYCAR SERIES Rookie of the Year campaign, driving the No. 45 Honda for Rahal Letterman Lanigan Racing. In his rookie season, he earned his first NTT P1 Award at Road America, recorded a season-best 11th place twice and finished 23rd in the championship standings.

The 2024 INDY NXT by Firestone champion won the title with Andretti Global, claiming eight wins, 12 podiums and six poles. He previously captured the 2022 Indy Pro 2000 championship and was a finalist for the Autosport BRDC Award. Foster began karting at age nine, winning club championships at Camberley Kart Club and Forest Edge Kart Club in 2013 and 2015.

Hailing from Odiham, England, Foster now resides in Indianapolis. He is the son of former British Touring Car Championship racer Nick Foster and enjoys watching racing — particularly past INDYCAR SERIES events, Formula 1 and BTCC — and following friends competing globally. Off track, he enjoys the gym, sim racing and cycling; in 2017, he rode across Snowdonia and the Brecon Beacons to raise funds for CRY.
